Consistent Scene Editing by Progressive Difference Images
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Even though much research was dedicated to the acceleration of consistent, progressive light transport simulations, the computation of fully converged images is still very time-consuming. This is problematic, as for the ... -
Extracting Microfacet-based BRDF Parameters from Arbitrary Materials with Power Iterations
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We introduce a novel fitting procedure that takes as input an arbitrary material, possibly anisotropic, and automatically converts it to a microfacet BRDF. Our algorithm is based on the property that the distribution of ... -
Illumination-driven Mesh Reduction for Accelerating Light Transport Simulations
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Progressive light transport simulations aspire a physically-based, consistent rendering to obtain visually appealing illumination effects, depth and realism. Thereby, the handling of large scenes is a difficult problem, ... -
Improved Half Vector Space Light Transport
(The Eurographics Association and John Wiley & Sons Ltd., 2015)In this paper, we present improvements to half vector space light transport (HSLT) [KHD14], which make this approach more practical, robust for difficult input geometry, and faster. Our first contribution is the computation ... -
Manifold Next Event Estimation
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We present manifold next event estimation (MNEE), a specialised technique for Monte Carlo light transport simulation to render refractive caustics by connecting surfaces to light sources (next event estimation) across ... -
Path-space Motion Estimation and Decomposition for Robust Animation Filtering
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Renderings of animation sequences with physics-based Monte Carlo light transport simulations are exceedingly costly to generate frame-by-frame, yet much of this computation is highly redundant due to the strong coherence ... -
Portal-Masked Environment Map Sampling
(The Eurographics Association and John Wiley & Sons Ltd., 2015)We present a technique to e ciently importance sample distant, all-frequency illumination in indoor scenes. Standard environment sampling is ine cient in such cases since the distant lighting is typically only visible ... -
Stochastic Soft Shadow Mapping
(The Eurographics Association and John Wiley & Sons Ltd., 2015)In this paper, we extend the concept of pre-filtered shadow mapping to stochastic rasterization, enabling real-time rendering of soft shadows from planar area lights. Most existing soft shadow mapping methods lose important ... -
Unifying Color and Texture Transfer for Predictive Appearance Manipulation
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Recent color transfer methods use local information to learn the transformation from a source to an exemplar image, and then transfer this appearance change to a target image. These solutions achieve very successful results ...
